DETAILED DESCRIPTION

In the following, only certain exemplary embodiments are brieflydescribed. As can be recognized by those skilled in the art, variousmodifications can be made to the described embodiments without departingfrom the spirit or scope of present disclosure. Therefore, the drawingsand the description are regarded as exemplary intrinsically rather thanrestrictive.

A folding mechanism 100 for a treadmill 1 and the treadmill 1 aredescribed below according to an embodiment of the present disclosurewith reference to FIGS. 1-7 .

As shown in FIG. 1 , the folding mechanism 100 according to theembodiment of the present disclosure includes a standpipe 10 and a dialframe 20.

Specifically, the first end of the standpipe 10 is provided with aconnection portion 11, and the connection portion 11 is provided with ahinge hole 111 and a limiting hole 112. The dial frame 20 includes abody 20 a, the body 20 a is provided with a hinge portion 21 and alimiting portion 22 spaced apart from each other, the hinge portion 21is pivotally connected to the hinge hole 111, and the limiting portion22 includes a movable limiting member 221. The dial frame 20 is rotatedrelative to the standpipe 10 between the first position and the secondposition. In a case where the dial frame 20 is in the second position,the limiting member 221 and the limiting hole 112 form a limiting fit.

In the embodiment of the present disclosure, the folding mechanism 100may be used for the treadmill 1. In a case where the folding mechanism100 is in a use state, the dial frame 20 is in the first positionrelative to the standpipe 10; and, in a case where the folding mechanism100 is in a storage state, the dial frame 20 is in the second positionrelative to the standpipe 10.

In an example, the folding mechanism 100 can be mounted to the base 200of the treadmill 1. The standpipe 10 can be fixedly arranged on the base200, or can be rotated relative to the base 200. In a case where thetreadmill 1 is in the use state, the standpipe 10 may be arranged to beinclined at an acute angle or vertical relative to the base 200, and thedial frame 20 may rotate within a certain angle range relative to thestandpipe 10. The dial frame 20 is used to mount a display device and/ora control panel of the treadmill 1.

Exemplarily, the first end of the standpipe 10 may be the upper end ofthe standpipe 10, the connection portion 11 is sleeved on the upper endof the standpipe 10, and the connection portion 11 is provided with thehinge hole 111 and the limiting hole 112 spaced apart from each other.The hinge portion 21 of the body 20 a is provided with a pivot holecorresponding to the position of the hinge hole 111, and a rotatingshaft 12 is arranged to pass through the hinge hole 111 and the pivothole, such that the hinge portion 21 is rotatable relative to theconnection portion 11, and thereby the body 20 a is rotatable relativeto the standpipe 10.

The rotation radius formed between the hinge portion 21 and the limitingportion 22 is consistent with the distance between the hinge hole 111and the limiting hole 112, such that in a case where the dial frame 20is rotated to the second position, the position of the limiting portion22 corresponds to the position of the limiting hole 112, thereby forminga limiting fit.

In an example, the limiting member 221 can reciprocate along a presetdirection, and at least a part of the limiting member 221 is located inthe limiting hole 112 to form a latch fit, so as to form a lock betweenthe dial frame 20 and the standpipe 10; or, the limiting member 221 isdisengaged from the limiting hole 112, thereby releasing the lockbetween the dial frame 20 and the standpipe 10. The limiting member 221can be configured as a column, and the preset direction can be the axialdirection of the limiting member 221.

It can be understood that the first position and the second positionrefer to the positions of the dial frame 20 relative to the standpipe10. For example, as shown in FIG. 2 , the first position may be aposition to which the dial frame 20 is rotated such that an includedangle of the dial frame 20 relative to the standpipe 10 is 60 degrees;as shown in FIG. 3 , the second position may be a position to which thedial frame 20 is rotated such that an included angle of the dial frame20 relative to the standpipe 10 is 0 degree, that is, the dial frame 20,when being in the second position, is parallel to the standpipe 10.

It should be noted that, in other examples of the present disclosure,the first position and the second position may be adjustedcorrespondingly according to actual needs, which are not specificallylimited in the embodiment of the present disclosure.

According to the treadmill 1 of the embodiment of the presentdisclosure, by arranging the hinge hole 111 on the connection portion 11of the standpipe 10, by arranging the hinge portion 21 on the body 20 aof the dial frame 20, and by a pivotal fit between the hinge portion 21and the hinge hole 111, the dial frame 20 is rotated relative to thestandpipe 10 between the first position and the second position.Therefore, the dial frame 20 can be rotated to the first position whenthe folding mechanism 100 is used, and the dial frame 20 can be rotatedto the second position after being used, thereby facilitating thestorage of the folding mechanism 100. Furthermore, by arranging thelimiting hole 112 on the connection portion 11 of the standpipe 10 andarranging a movable limiting member 221 on the dial frame 20, in a casewhere the dial frame 20 is rotated to the second position, the positionof the dial frame 20 relative to the standpipe 10 is locked by alimiting fit between the limiting member 221 and the limiting hole 112,thereby improving the stability of the folding mechanism 100 in use. Inaddition, when the folding mechanism 100 needs to be stored, themovement of the limiting member 221 is controlled to disengage thelimiting member 221 from the limiting hole 112, thereby releasing thelock between the dial frame 20 and the standpipe 10; and then the dialframe 20 is rotated from the first position to the second position,thereby improving the convenience of the folding mechanism 100 duringstorage.

As shown in FIG. 1 , in an embodiment, the limiting portion 22 furtherincludes a first elastic member 222, and the first elastic member 222 isconfigured to apply an elastic force to the limiting member 221, suchthat the limiting member 221 is always in a locking position.

The locking position refers to a position where the limiting member 221can form a limiting fit with the limiting hole 112.

Exemplarily, the first elastic member 222 may include a spring, such asa compression spring or a tension spring. It can be understood that thecompression spring refers to a spring that is always in a compressionstate, and the compression spring applies its elastic force in thetension direction to the limiting member 221; and the tension springrefers to a spring that is always in a tension state, and the tensionspring applies its elastic force in the compression direction to thelimiting member 221.

In this embodiment, the specific arrangement manner of the first elasticmember 222 and the limiting member 221 is not specifically limited here,as long as the elastic force applied to the limiting member 221 by thefirst elastic member 222 in the deformed state is satisfied, such thatthe limiting member 221 is always in the locking position.

It should be noted that, in a case where the limiting member 221 is inthe locking position, the limiting member 221 and the limiting hole 112form a latch fit, such that a locking state is formed between the dialframe 20 and the standpipe 10. When it is necessary to release thelocking state between the dial frame 20 and the standpipe 10, the stateof the first elastic member 222 can be changed by applying an externalforce to the limiting member 221, such that the limiting member 221 canbe disengaged from the limiting hole 112, that is, the first elasticmember 222 moves from the locking position to the unlocking position.

According to the above-mentioned implementation, through the elasticforce of the first elastic member 222, the limiting member 221 can bealways in the locking position. Therefore, the position of the limitingmember 221 does not need to be adjusted manually, such that the limitingmember 221 and the limiting hole 112 automatically form a limiting fitwhen the dial frame 20 is rotated to the second position.

As shown in FIG. 1 , in an embodiment, the limiting portion 22 furtherincludes a first support plate 223 and a second support plate 224 thatare spaced apart. The first support plate 223 and the second supportplate 224 are connected to the body 20 a, and each of the first supportplate 223 and the second support plate 224 is provided with a throughhole, and the limiting member 221 is arranged to pass movably throughtwo through holes. The limiting member 221 is provided with a firstanti-disengagement portion 221 a and a second anti-disengagement portion221 b. The first anti-disengagement portion 221 a and the through holeof the first support plate 223 form an anti-disengagement fit, and thesecond anti-disengagement portion 221 b and the through hole of thesecond support plate 224 form an anti-disengagement fit. The firstelastic member 222 is sleeved on the limiting member 221, and both endsof the first elastic member 222 are respectively abutted between thefirst support plate 223 and the second anti-disengagement portion 221 b.The first elastic member 222 is always in a compression state andapplies an elastic force to the second anti-disengagement portion 221 b,such that the limiting member 221 is always in the locking position.

Exemplarily, the first support plate 223 and the second support plate224 are spaced apart in the length direction of the body 20 a, and thefirst support plate 223 and the second support plate 224 are inclineddownward from the lower surface of the body 20 a. The positions of thethrough hole on the first support plate 223 and the through hole on thesecond support plate 224 correspond to each other, such that thelimiting member 221 can slidably pass through the two through holes. Thefirst anti-disengagement portion 221 a is located on the side of thefirst support plate 223 away from the second support plate 224, and thesecond anti-disengagement portion 221 b is located between the firstsupport plate 223 and the second support plate 224. The first elasticmember 222 can include a compression spring, and both ends of the firstelastic member 222 are respectively abutted between the first supportplate 223 and the second anti-disengagement portion 221 b. Thecompression spring applies elastic forces on the first support plate 223and the second anti-disengagement portion 221 b respectively indirections away from each other, such that the second anti-disengagementportion 221 b always abuts against the second support plate 224.

Understandably, an anti-disengagement fit of the firstanti-disengagement portion 221 a and the through hole on the firstsupport plate 223, and an anti-disengagement fit of the secondanti-disengagement portion 221 b and the through hole on the secondsupport plate 224, mean that the shape or size of the firstanti-disengagement portion 221 a is larger than the shape or size of thethrough hole on the first support plate 223, and the shape or size ofthe second anti-disengagement portion 221 b is larger than the shape orsize of the through hole on the second support plate 224, such that thefirst anti-disengagement portion 221 a cannot pass through the throughhole on the first support plate 223, and the second anti-disengagementportion 221 b cannot pass through the through hole on the second supportplate 224, thereby serving to prevent the limiting member 221 from beingdisengaged from the through holes on the first support plate 223 and thesecond support plate 224.

In a specific example, the limiting member 221 is provided with twomounting holes spaced apart from each other, and the firstanti-disengagement portion 221 a and the second anti-disengagementportion 221 b are in an interference fit with the two mounting holesrespectively, so as to fix the first anti-disengagement portion 221 aand the second anti-disengagement portion 221 b to the limiting member221 respectively.

According to the above embodiment, the fit mounting of the limitingmember 221 and the first elastic member 222 is realized, and byarranging the first anti-disengagement portion 221 a and the secondanti-disengagement portion 221 b on the limiting member 221, thelimiting member 221 is prevented from being disengaged from the throughholes on the first support plate 223 and the second support plate 224,thereby improving the structural reliability of the limiting portion 22.

As shown in FIG. 1 , in an embodiment, the connection portion 11 is ahollow structure, the limiting hole 112 is arranged to pass through thewall of the connection portion 11, and the connection portion 11 isfurther provided with a first unlocking portion 113. The first unlockingportion 113 is movably arranged on the connection portion 11, and theposition of the connection portion 11 corresponds to the position of thelimiting hole 112. The first unlocking portion 113 is adapted to drivethe limiting member 221 to move under the action of an external force,such that the limiting member 221 and the limiting hole 112 are releasedfrom the limiting fit.

Exemplarily, the connection portion 11 is a hollow structure to define acavity inside thereof. In a case where the dial frame 20 is in thesecond position, the limiting portion 22 of the dial frame 20 is locatedin the cavity, and the free end of the limiting member 221 protrudes outof the cavity through the limiting hole 112, such that the limitingmember 221 and the limiting hole 112 forms a limiting fit. The firstunlocking portion 113 is arranged outside the cavity and corresponds tothe position of the limiting hole 112, such that the first unlockingportion 113 can contact the free end of the limiting member 221. Thefirst unlocking portion 113 drives the limiting member 221 to move underthe action of the external force, such that the limiting member 221 isdisengaged from the limiting hole 112, thereby releasing the limitingfit between the limiting member 221 and the limiting hole 112.

According to the above implementation, the user can apply an externalforce to the first unlocking portion 113 by pressing the first unlockingportion 113, that is, the limiting member 221 can be driven to move bythe first unlocking portion 113, thereby releasing the limiting fitbetween the limiting member 221 and the limiting hole 112; and then thedial frame 20 is rotated from the second position to the first position,thereby further improving the convenience of the folding mechanism 100during storage.

As shown in FIG. 2 , in an implementation, in a case where the dialframe 20 is in the second position, the dial frame 20 and the standpipe10 are arranged parallel to each other and in a fitting state.

Illustratively, the dial frame 20 is adapted to be constructed as a flatplate structure. In a case where the dial frame 20 is in the secondposition, the length direction of the dial frame 20 and the lengthdirection of the standpipe 10 are parallel to each other, and the lowersurface of the dial frame 20 and the outer surface of the standpipe 10are in a fitting state of each other.

Through the above implementation, in a case where the dial frame 20 isrotated to the second position, the fitting degree between the dialframe 20 and the standpipe 10 is improved, the overall size of the dialframe 20 and the standpipe 10 is reduced, the space occupation isreduced, and thereby the storage effect of the folding mechanism 100 isimproved.

As shown in FIG. 2 and FIG. 3 , in an implementation, the side surfaceof the body 20 a facing the standpipe 10 is further provided with abuffer member 23. In a case where the dial frame 20 is in the secondposition, the buffer member 23 is in contact with the standpipe 10.

Exemplarily, the material of the buffer member 23 may include a softmaterial, such as rubber.

Through the above implementation, when the dial frame 20 is rotated tothe second position, a certain buffer effect can be achieved through thecontact between the buffer member 23 and the standpipe 10, so as toavoid the direct collision between the dial and the standpipe 10,thereby having a certain protective effect.

As shown in FIGS. 1 and 2 , in an implementation, in a case where thedial frame 20 is in the second position, the lower surface of the body20 a is supported on the upper end surface of the connection portion 11.

Exemplarily, both the lower surface of the body 20 a and the upper endsurface of the connection portion 11 are configured as planes, and theupper end surface of the connection portion 11 is arranged in parallelwith the horizontal plane. Accordingly, in a case where the dial frame20 is in the second position, the lower surface of the body 20 a is insurface contact with the upper end surface of the connection portion 11,and the body 20 a is parallel to the horizontal plane.

Through the above implementation, in a case where the dial frame 20 isin the second position, the contact area between the body 20 a and theconnection portion 11 is increased, thereby improving the supportingeffect of the standpipe 10 to the dial frame 20, and further improvingthe stability of the dial frame 20 in the second position.

As shown in FIG. 4 , in an implementation, there are two standpipes 10that are arranged side by side and spaced apart, and the dial frame 20further includes two armrest portions 20 b corresponding to the twostandpipes 10 respectively. The two armrest portions 20 b are formed byextending from the body 20 a in the same direction, and each of the twoarmrest portions 20 b is provided with a hinge portion 21 and a limitingportion 22.

Exemplarily, the two armrest portions 20 b are spaced apart in the widthdirection of the body 20 a, and each of the two armrest portions 20 b isformed by extending rearwardly from the rear side edge of the body 20 a.The two armrest portions 20 b and the rear side edge of the body 20 atogether define an active space. Each of the first ends of the twostandpipes 10 is provided with a connection portion 11, and is rotatablyconnected with a respective corresponding armrest portion 20 b throughthe connection portion 11. Each of the second ends of the two standpipes10 is fixed or rotatably connected to the base 200 of the treadmill 1.

Through the above implementation, on the one hand, the stability of theoverall structure of the folding mechanism 100 is improved, such thatthe support by the two standpipes 10 is more stable when the dial frame20 is in the first position; on the other hand, by providing the armrestportions 20 b respectively connected to the two standpipes 10, thesupport can be provided for the user's hands when the user uses thetreadmill 1, thereby improving the usage experience of the user.

As another aspect of the embodiment of the present disclosure, theembodiment of the present disclosure further provides a treadmill 1.

Exemplarily, in a case where the standpipe 10 is in the open position,there is a preset included angle between the length direction of thestandpipe 10 and the plane where the base 200 is located; wherein thepreset included angle can be 60 degrees. In a case where the standpipe10 is in the folding position, the included angle between the lengthdirection of the standpipe 10 and the plane where the base 200 islocated can be 0 degree, that is, the standpipe 10 is arranged parallelto the base 200.

It can be understood that the included angle of the standpipe 10relative to the base 200 in the open position and the folding positioncan be specifically set according to the actual situation, which is notspecifically limited in the embodiment of the present disclosure.

Further, as shown in FIG. 2 , when the treadmill 1 is in use, thestandpipe 10 can be rotated to the open position, and the dial frame 20can be rotated to the first position; as shown in FIG. 7 , when thetreadmill 1 is stored, the dial frame 20 can be rotated to the secondposition and the standpipe 10 can be rotated to the folding position.

According to the treadmill 1 of the embodiment of the presentdisclosure, by using the folding mechanism 100 according to theabove-mentioned embodiment of the present disclosure and rotatablyarranging the standpipe 10 of the folding mechanism 100 on the base 200,the structural stability of the treadmill 1 during use and theconvenience of the treadmill 1 during storage are improved, and theoverall size of the treadmill 1 can be reduced as much as possibleduring storage, thereby reducing the occupation of storage space.

As shown in FIG. 4 and FIG. 5 , in an implementation, the second end ofthe standpipe 10 is provided with a rotating shaft 12 that rotatablyfits in with the base 200, the end of the rotating shaft 12 is connectedwith a locking member 13, and the locking member 13 is rotatedsynchronously with the rotating shaft 12. The base 200 is furtherprovided with a movable locking fit portion 30, and the locking fitportion 30 is provided with a locking fit groove 30 a. In a case wherethe standpipe 10 is in the open position or the folding position, thelocking member 13 and the locking fit groove 30 a form a limiting fit.

Exemplarily, the base 200 is provided with a pivot through hole, and therotating shaft 12 at the second end of the standpipe 10 pivotally passesthrough in the pivot through hole. The locking member 13 is fixedlyconnected to the free end of the rotating shaft 12 and is rotatedsynchronously with the rotating shaft 12. The locking fit portion 30 isadapted to move between the locking position and the unlocking position,and the locking fit portion 30 is always in the locking position, suchthat at least a part of the locking member 13 is embedded in the lockingfit groove 30 a of the locking fit portion 30, thereby forming thelimiting fit.

It can be understood that in a case where the locking member 13 and thelocking fit groove 30 a form the limiting fit, the standpipe 10 cannotrotate relative to the base 200, such that the standpipe 10 is kept inthe open position or the folding position. When it is necessary torotate the standpipe 10 from the open position to the folding position,or from the folding position to the open position, the limiting fitbetween the locking member 13 and the locking fit groove 30 a isreleased by controlling the movement of the locking fit portion 30 todisengage the locking member 13 from the locking fit groove 30 a, suchthat the standpipe 10 can be rotated relative to the base 200.

Through the above implementation, the structural stability of thestandpipe 10 can be improved during the use of the treadmill 1, that is,when the standpipe 10 is in the open position; and when it is necessaryto store the treadmill 1, the movement of the locking fit portion 30 iscontrolled to unlock the standpipe 10, so that the standpipe 10 isrotated to the folding position, thereby improving the convenience whenstoring the treadmill 1.

As shown in FIG. 4 and FIG. 5 , in an implementation, the locking fitportion 30 includes a link mechanism 31. A first end of the linkmechanism 31 is provided with a locking fit groove 30 a, and a secondend of the link mechanism 31 is provided with a second unlocking portion32. The second unlocking portion 32 drives the locking fit groove 30 ato be engaged with or disengaged from the locking member 13 under theaction of an external force.

Exemplarily, the link mechanism 31 includes a first link 311, a secondlink 312, and a third link 313 which are connected in sequence. Thefirst end of the first link 311 is the first end of the link mechanism31, and the first end of the first link 311 is provided with the lockingfit groove 30 a. The second end of the first link 311 rotatably fits inwith the first end of the second link 312. The first link 311 isprovided with a rotating shaft between the first end and the second endthereof, and the rotating shaft is rotatably arranged on the base 200.Therefore, the first link 311 can be rotated relative to the base 200.The first end of the third link 313 rotatably fits in with the secondend of the second link 312, the second end of the third link 313 is thesecond end of the link mechanism 31, and the second end of the thirdlink 313 is provided with a second unlocking portion 32. The third link313 is provided with a rotating shaft between the first end and thesecond end thereof, and the rotating shaft is rotatably arranged on thebase 200, such that the third link 313 can be rotated relative to thebase 200.

It can be understood that, by applying an external force to the secondunlocking portion 32 at the second end of the third link 313, the thirdlink 313 can drive the first link 311 to rotate through the second link312, and then, the position of the locking fit groove 30 a at the firstend of the first link 311 can change, such that the locking fit groove30 a and the locking member 13 form a limiting fit or a disengagementfit.

According to the above implementation, by the user stepping on thesecond unlocking portion 32 to apply an external force to the secondunlocking portion 32, the position of the locking fit groove 30 a can bedriven to change through the link mechanism 31, thereby releasing thelimiting fit between the locking member 13 and the fit groove, andthereby further improving the convenience of the treadmill 1 duringstorage.

As shown in FIG. 5 , in an implementation, the locking fit portion 30further includes a second elastic member 33, and the second elasticmember 33 is configured to apply an elastic force to the second end ofthe link mechanism 31, such that the locking fit groove 30 a is alwaysin the locking position where the locking fit groove 30 a is in thelimiting fit with the locking member 13.

Exemplarily, the second elastic member 33 can include a tension spring,one end of the tension spring is connected to the second end of thethird link 313, and the other end of the tension spring is connected tothe base 200, such that the tension spring always applies the elasticforce to the third link 313, and through the link mechanism 31, thelocking fit groove 30 a at the first end of the first link 311 is alwaysin the locking position.

According to the above implementation, by the effect of the elasticforce of the second elastic member 33, the locking fit groove 30 a canbe always in the locking position. Therefore it is not necessary tomanually adjust the position of the locking fit groove 30 a, such thatin a case where the standpipe 10 is in the folding position or the openposition, the locking member 13 and the locking fit groove 30 aautomatically form a limiting fit.

As shown in FIG. 6 , in an implementation, the treadmill 1 furtherincludes a buffer air pressure rod 40. The first end of the buffer airpressure rod 40 is rotatably connected to the base 200, and the secondend of the buffer air pressure rod 40 is rotatably connected to thelocking member 13.

Exemplarily, the first end of the buffer air pressure rod 40 is a fixedend of the buffer air pressure rod 40, and the fixed end of the bufferair pressure rod 40 is rotatably fixed to the base 200. The second endof the buffer air pressure rod 40 is a telescopic end of the buffer airpressure rod 40, and the telescopic end of the buffer air pressure rod40 is rotatably fixed to the locking member 13.

It can be understood that during the rotation of the standpipe 10 fromthe open position to the folding position, the telescopic end of thebuffer air pressure rod 40 moves along the direction of contraction, andthe standpipe 10 is rotated slowly through the air pressure buffereffect inside the buffer air pressure rod 40.

Through the above implementation, during the rotation of the standpipe10 from the open position to the folding position, a certain buffereffect can be provided to the standpipe 10, to prevent the standpipe 10from directly rotating toward the base 200 to cause a collision, so asto have a certain protective effect on the standpipe 10 and the base200.

As shown in FIG. 7 , in an implementation, in a case where the standpipe10 is in the folding position relative to the base 200 and the dialframe 20 is in the second position relative to the standpipe 10, boththe dial frame 20 and the standpipe 10 as well as both the standpipe 10and the base 200 are arranged parallel to each other and in a fittingstate.

Exemplarily, there are two standpipes 10 and the two standpipes 10 arerespectively provided on both sides of the base 200 in the widthdirection. In a case where the standpipe 10 is in the folding position,the two standpipes 10 are arranged in parallel to the base 200 and arelocated on both sides of the base 200 in the width direction,respectively. Meanwhile, the dial frame 20 is in the second position,and the dial frame 20 is arranged parallel to the base 200.

Further, the dial frame 20 is further provided with a rotatable displaydevice. In a case where the dial frame 20 is in the second position, thedisplay device can be rotated to a position parallel to the base 200.

Through the above implementation, when the treadmill 1 needs to bestored, by rotating the standpipe 10 to the folding position androtating the dial frame 20 to the second position, the size of thetreadmill 1 in the height direction is reduced to the greatest extent,thereby further improving the storage effect of the treadmill 1.
